' T all whom it may concern:

Be it known that I, ANTON SOHIEFERSTEIN,

a citizen of the United States, and a resident of Bayonne, in the county of Hudson and State'of New Jersey, have invented certain new and useful Improvements in Hydrocarbon-Engines, of which the following is a specification. i

This invention relates to improvements in hydrocarbon engines, petroleum engines, gas engines and the like. Its organization comprises essentially a pair of com ression'cylinders, in each of which a pair oFpistons-operate opposite each other, for compressing the charges; a air of exploding or power cylin ders, in eac of which a pair of power pistons operate opposite each other; an inlet valve for each power cylinder, controlled by the pistons of its accompanying compressioncyl- 1nder;air inlet valves in each end of each power cylinder, and transfer valves in each piston of the power cylinders; an exhaust valve for each power cylinder; connections between the adjacent pistons of the power cylinder; connections between the distant pistons of the power cylinders, and similar connections between the pistons of the compression cylinders and means for exploding the charge-: in the power cylinders.

Fig. 9 shows a front elevation of the righthand end of a portion of the sleeve 40, Fig. 10 is a front elevation of the left-hand end of a portion of the sleeve 46, Fig. 11 is an end view ofFig. 10 and Fig. 12 is an end view of Fig. 9, Fig. 13 is a cross-section of a modification of the invention' and appurtenances, Fig. 14 shows a section of Fig. 13 on the line 14, 14, Fig. 15 represents a partial section of Fig. 14 on the line 15, 15, Fig. 16- is atop-view of a portion of Fig. 13, Fig. 17 shows apartial section. of Fig. 1 on the line 17, 17, and Fig. 18 isa partial side view of Fig. 1.

A carburetor is shown at 20, from which lead the pipes 21 and 22; To the pipe 21 is connected the valve chamber 23 for the inlet valve 24, and to the pipe 22 is connected the valve chamber 25 withthe inlet valve 26. A cage 27 is secured in an opening of the compression cylinder 28, and a cage 29 is secured in an opening in the compression cylinder 30.

The cage 27 has formed therewith the sleeve 31, which at its left hand end guides and supports the spindle 32 of the valve 24. A shoulder 33 is formed on the cylindrical surface of the sleeve 31, for the s ring 34 which bears between the said shou der and the said valve 24.

The right hand end of the sleeve'rwl sup- 7 ports the valve spindle 35 of the valve 36, which latter opens into the power cylinder 37 A cage 38 is supported between the cylinders 2S and 37, and it has formed therewith the sleeve 39, which supports and guides the right hand end of the valve spindle 35.

To the spindle 35 is secured the sleeve 40 with the pin 41, and its right hand end is cut away through a planepassing through its longitudinal axis, as shown at 42 and its right hand edges 43 and 44 are formed into approximately helical surfaces. In one of the said edges is journaled the roller 45. On the other end of the spindleis supported the sleeve 46, whichhas its left hand end cut away, as shown at 58, similar to 42 of theslceve 40. The left hand edges of the sleeve 46 have the helical surfaces 47 and 48, and in the latter is journaled the roller 49. A portion of the edges of each sleeve is at right angles to the longitudinal axis of the spindle as shown at 50 and 5.1, and againstthis ortion the roller of the other sleeve bears, w ion the sleeves are spread apart from each other as far as they can be moved. The sleeves are joined by the spring 52 which tends to keep them apart and locks the valve 36. Extending from each sleeve and radially therefrom are pins '53 and 54. The right hand end of the sleeve 46 terminates in the threaded end 55 on which are supported a pair of jam nuts 56 and 57, that bear against the cage 38 for adjustment.

The compression cylinder 30 is connected to the power cylinder 60, with a cage 61 similar to the cage 38. The valve 26 with its appurtenances is similar to the valve 24 and its a purtenances. An inlet valve 62 for the cy inder is similar and has appurtenances for its operation which are similar to those of the valve 36.

The power cylinder 60, contains the pieton 63, with the transfer valves 64, and in the head are supported the inlet val es 66. In the piston 67 are the transfer valves 68 similar to the valves 64, and in the cylinder head 69 are the inlet valves 70 similar to the valves 66. Transfer valves 71 and 72 are located respectively in the pistons 73 and 74 similar to the valves in the pistons of the cylinder 60, and inlet valves 75 and 76, are respectively located in the cylinder heads 77 and 78 of the ower cylinder 37.

The inlet va ves 66, 70, 75 and 76 in Fig. 1 are shown in a plane at right angles to their locations as shown in Fig. 8 to avoid confusion, and the location in Fig. 8 is the correct one, so as to give clearance for some of the moving parts of the engine.

A piston rod 80, connects the two pistons 67 and 73, a boss 81 being formed in the rod 80, and a stufling box 82 is located for the rod in the cylinder head 69, and a stufling box 83 is formed in the cylinder head 77.

A crank shaft 85 is supported in bearings 86, 87, 88, and at the right hand end on its pin 89 is carried the link 90, which carries a pin 91, that supports theboss 92 of the piston rod 93 of the piston 63. A stuifing box 94 for the rod 93 is formed in the cylinder head 65. The pin 91 also carries the boss 95 of the bow 96, which latter at its other end has formed therewith the boss 97, that carries a pin 98 for the boss 99 of the piston rod 100 connected to the piston 74. A stuffing box 101 is formed in. the cylinder head 78 for the piston rod 100. On the crank pin 102 is carried the link 103, from which latter extends the pin 104, that supports the bow 105. The latter is pinned with a pin 106 to the boss 81 of the piston rod 80.

On the pin 107 is supported the link 108, which carries a pin 109, and on the latter is supported the boss 110 of the'piston rod 111, of the piston 112 in the cvlinder 30, a guide 113 being supported at the end of the cylinder 30 for the piston rod 111. From the pin 109 extends the bow 114, which latter connects with the pin 115, that supports the boss 116 of the piston rod 117. The piston rod 117 reciprocates through a guide 118 located at the outer end of the cylinder 28, and to the piston rod 117 is fastened the piston 1 18. From the pin 119 of the crank shaft 85, extends the link 120, to which is connected with the .pin 121 which supports one end of the how 122, the other end of which latter carries the pm 123, that extends through the boss 124 of the piston rod 125. The piston 126 of the cylinder 28 is connected to the rod at one end, and the piston 127 in tliecylinder 30 is connected to the same at the other end. Guides 129 and 130 are connected to the cylinders 28 and 30 for the rod 125, The bow 96 is supported on guides 131, and thebow 105 on guides 132, extending from the cylinders 37 and 60. The bow 122.

is supported in guides 1 33, and the bow 114 the bracket 135, and the cylinders 30 and 60 by the bracket 136. The cylinders 28 and 30 are connected by the bracket 137, and the cylinders 37 and 60 are connected by the bracket 138.

of the pistons 112, 127, 126 and 118 there of a-hinge 142, and a spring 143 bears up against the back of the hinge 142 and is sup orted on the piston.

For each of the cy inders 37 and 60 there is an exhaust valve 144, the spindle. 145 of which is actuated by an arm 146 of a bell crank 148. Each of the bell cranks is carried on apin 149, supported in the brackets 150 that extend from the cylinders 37'and 60. A cam shaft 151 is supported in bearings 152 formed in the brackets 150, and it has a support 153 extending from the hearing 88. The shaft 151 carries cams 154, that actuate rollers 155 in the arms 156 of the bell crank 148. A bevel gear 157 on the shaft 85 meshes with a bevel gear 158, on the cam shaft 151. v

It will be noted that the arms 160 and 161 of the crank shaft 85 are set withrespect to the arms 162 and 163, so that the, pistons in the compression cylinders 28 and30 are a little ahead of the istons in the power cylinders 37 and 60. lso that when the pistons in the cylinder 60 are approaching eac other, the pistons in the cylinder 37 are receding from each other, also when the pistons in the cylinder 30 are approaching each other, the pistons in the cylinder 28 are receding from each other. The relations of the arms of the crank shaft as just described may be varied. c

To explode the com' ressed charges'in the power cylinders 37 an 60, there is provided for each, a spark plug 195, each of which is controlled by a contact breaker 196 in the usual nianner.

Figs. 13 to'16 show a modification of the invention, and there is shown a cross section -of a compression cylinder with an inlet valve 171. A power cylinder 172 is conper 141, by means by means of the valve chamber 173. A dividing wall 174 divides the valve chamber 173 into two compartments 181 and 182, and a communicating chamber 183 is formed below the dividing wall 174. A valve 175 opens from the communicating chamber 183 into the compartment 181, and a valve 176 opens from the chamber 183 into the compartment 182.

A journal bracket 177 in the compartment 181 supports a lever 178, that at one end The cylinders 28 and 37 are connected by On the face opposite the piston rod of each bears up against a collar 179 on the spindle projects a post 140, to which is hinged a tripnected with the compression cylinder 170,

180 of the valve 175, and at the other end it said piston, and bears against the tripper. An inclined PIOJQCUOII 190 extends from the tripper which engages Wlth the roller 191 carried on the lever 178.

To operate the engine the charges of gas are'furnished by the. carburetor 20, and when the pistons in the compressing cylinder 28, and thepistons in the cylinder are receding l'roin'each other the valves 24 and 26 are respectively drawn open, and the said cylinders are charged with the exploding mixture.- W hen the pistons in cylinders 28 and 30 approach each other, the charges therein are (SUIIIPIGSSQil, and when the tri pcrs 141strike the hooks as 53 and 54, tic

valves36 and 62 are opened, and the charges are forced into the power cylinders 37 and 60,

-where dthey are further compressed by the pistons therein, and then are lgnited by the spark plugs.

The operatlons of the valves 36 and 62 being similar the operations of the former will only lie-described in detail. When the trippers 141 strikenthe hooks 53 and 54, the

ho 53*will be pushed down and the hook 64. will be pushed up, the effect of which will be to rotate the valve spindle with its "sleeve 40 in the direction of the rotation of the hands ofa'watch and to rotate-the sleeve 46 in a direction opposite thereto. Before the trippers strike the said hooks the relative and normal positions of the sleeves 40 and "46 are plainly shown in Fig. 3, and in said normal positions the roller 49 of the sleeve 46 is bearingagainst the edge 50 of the sleeve 40, which edge. being at right angles to the longitudinal axis of thesleeve maintains the roller49 in position, without danger of rolling off said edge. At the same time the roller 45 of the sleeve 46 bears against the edge 51 of the sleeve 46 which latter edge is at right angles to the longitudinal axis of its sleeve. The combinations of the rollers 49, 45 with the edges '50and 51 constitute locking devices for the sleeves .46 and 46 and consequently for thevalve hen the trippers 141st1ike the books .53, 54, the roller 49 rolls on the helical jedge43 and the roller 45 rolls on the helical edge 47 which will cause the sleeves 4'0 and 46 'to rotate relatively to each other. The rotation of the sleeves is osslble on account of the clearance space etween them incident to the cut away portions indicated at 42 and When the said sleeves rotate one approaches each other in the direction of their common longitudinal axis. jlhe sleeve 46 being able to rotate on the spindle 35, and the sleeve 40 being fastened to the spindle 35,

the latter sleeve with its spindle will approach the sleeve 46 and open the valve 36. The trippers afterpushing the books. 53 and 54 out of the way pass beyond them, when the spring 52 will cause the sleeve 40 with the spindle 35 and valve 36 to take its normal position with the latter on its seat. The trippers 141 are allowed to move away from the hooks 53 and 54 by reason of the action of the hinge 142.

It is to be noted that any form of exploder may be used. After the gases have been exploded they are forced out of the openings of the exhaust valves.

It will be noted that when the pistons 63, 67 in the cylinder are approaching each other, that the inlet valves 66 and 70 are drawn open, and air is drawn into the cylinders between the head and the piston 63, and between the head 69 and the piston 67, and that when the pistons 63 and 67 recede from each other, the air between the pistons and the heads of the cylinder is pocketed therein by reason of the valves 66 and 70 closing. Now when the exhaust valve has opened the cylinder 60 is released of any pressure between the inner faces of the pistons, which occurs somewhat before the ends of the outward strokes of the pistons therein, and when the pressure of the compressed air between the pistons in the cylinder and its heads, exceeds the pressure between the pistons, the transfer valves 64 and 68 will allow the air to take the place of the spent gases in the cylinder, which will cool the cylinder and displace all of the spent gases, and finally will leave the cylinder by way of the exhaust valve. The same action takes place in the cylinder 37.
